Rose Marie was a child star before Shirley Temple was born, sang for Al Capone, opened the first big casino in Las Vegas and changed the world by playing a female writer on “The Dick Van Dyke Show” when women didn't work on TV. Spanning vaudeville, radio, Broadway, film, television and more, this new documentary tells the story of the longest active career in entertainment, but it also looks at what it was like to be a female performer in the 20th century, how to work through periods of extreme personal heartbreak and how Rose Marie and her fellow nonagenarians Dick Van Dyke, Carl Reiner and Peter Marshall still have the drive to create today. Along with interviews from such celebrated colleagues, the film contains amazing behind-the-scenes color footage from Rose Marie's personal collection, chronicling what went on backstage on "The Dick Van Dyke Show" and other sets where she worked.
